Official Facebook app for Windows Phone updated

The official Facebook app for Windows Phone has been lagging behind other platforms, but a new version has been released. The Facebook app for Windows Phone has been updated to version 5.1 and adds some photo features to the client. The biggest new feature is the ability to batch upload photos to messages. Those who use Facebook Messenger a lot will find this handy, as it doubles as a MMS client.

Version 5.1 also adds tagging and better navigation, as well as the ability to unlike or unfriend people from the app. It's still way behind iOS and Android, but at least they're making progress.
